Layout Analysis — C

Overview

Layout analysis uses AI technology to parse and understand the structure of a document layout. It extracts text, images, tables, layers, and other data from input documents.

Features that support Layout Analysis:

• PDF to Word
• PDF to Excel
• PDF to PowerPoint
• PDF to HTML
• PDF to RTF
• PDF to TXT
• PDF to CSV
• Extract PDF to JSON
• Extract PDF to Markdown

Notice

• You need to load the DocumentAI model before using layout analysis, or plug in your own AI engine via callbacks described in 4.11 Use Custom AI Models via Callbacks.
• When OCR is enabled, layout analysis is automatically enabled.
• AI table recognition is a separate stage controlled by enable_ai_table_recognition.

Sample

CPDF_SetDocumentAIModel(CPDF_TEXT("path/documentai.model"), -1);

CConvertOption option = CPDF_DefaultConvertOption();
option.enable_ai_layout = true;

CPDF_StartPDFToWord(CPDF_TEXT("word.pdf"), CPDF_TEXT("password"), CPDF_TEXT("path/output.docx"), option, NULL);
